“The Messenger of Allah has said, ‘Over and above every virtuous deed there is a virtuous deed, up to a man’s accepting martyrdom and being killed for the cause of Allah. When he is killed for the cause of Allah, then there is no virtuous deed over and above it. Also, over and above every sin of causing suffering and disappointment to parents there is another sin until a man murders one of his parents, and when he does this there is nothing above this sin in the sins of causing suffering to parents.’”
